Player calibration isn't saving
 

i bought a cheap chinese Innovatek mp4 player with camera capabilities from MP3PlayerStore.com Bluetooth GPS Car DVD Player MP5|MP4|MP3 Player | Car PC TV LCD Monitor last year. so far it had been working great, except the games dont work and the touchscreen isnt calibrated right. when i go into calibration settings, it wont save them.

i thought maybe its time to re-flash a different, more reliable firmware onto it. but i dont want the end result to be a dead player and i cant seem to find anyone who knows what firmware to use on this player.
